Corning, a large glass supplier, has a specialty materials unit that has seen sales surge in recent quarters as demand for smartphones, tablets and laptops have sparked Gorilla Glass sales. In the second quarter, Corning’s specialty materials business delivered sales of $283 million, up 125 percent from a year ago.

We no longer believe that Corning Gorilla Glass sales this year have the potential to reach $1 billion. Rather, we expect sales will be in the area of $800 million. This adjustment is driven by our realization that television cover glass sales will not be as strong as we originally hoped.

The display industry has been behaving more cautiously in recent weeks, driven primarily by weaker retail expectations for the second half. We have seen many LCD TV brands reduce their sales forecasts for the year. As LCD panel manufacturers have taken a more measured approach to their supply chain demands, they may be waiting a little longer to raise panel fab utilization for seasonal fourth-quarter retail demand.

Corning reported second quarter earnings of $755 million, or 47 cents a share, on revenue of $2 billion. Non-GAAP earnings of 48 cents a share were a penny ahead of Wall Street estimates.

Correction: The original version of this misstated the connection between the LCD market and Gorilla Glass. Although Gorilla Glass will be an $800 million business it is still growing strongly. We regret the error.
